basic information
Our OPTCOM business division will be inherited from Optocom Co., Ltd. We provide measurement systems for integrating spheres, photometric measurement systems, growth light sources for plants and animals, and various measurement services, including the measurement of electrical and optical characteristics of LED lighting! High-precision measurement devices with simple operation. The total luminous flux measurement system can measure light sources with 2π and 4π luminous distribution in accordance with the measurement standards LM-78 and LM-79 set by IESNA (Illuminating Engineering Society of North America). Additionally, as a calibration function, self-absorption correction and spectral sensitivity configuration can be performed using measurement methods compliant with JISC8152. We measure the total luminous flux of lighting sources such as LED lighting, LED backlights, and organic EL with high precision and simple operation. 【Measurement Items】 ○ Total luminous flux (LF [lm]) ○ Radiant flux (RF [W]) ○ Luminous efficacy (LE [lm/W]) ○ Chromaticity (CIE x, y), (CIE u, v), (CIE u’, v’) ○ Correlated color temperature (Tcp [K]) ○ Deviation from black body radiation trajectory (Duv) ○ Color rendering index (CRI) ○ Spectral radiant intensity spectrum ([W/nm]) ○ Main wavelength and information on each peak (half-width), etc.
